  const toggleSwitch = () => setIsEnabled(previousState => !previousState);

  const _goBack = () => console.log('Went back');

  const _handleSearch = () => console.log('Searching');

  const _handleMore = () => console.log('Shown more');

  return (
    <Provider>
    <Appbar.Header style={styles.header}>
      <Appbar.BackAction onPress={_goBack} />
      <Appbar.Content title="Mywebtuts" subtitle="Subtitle" />
